How can I tell if my iMac logic board is dead
my iMac will not boot. I have seen the symptoms of impending logic board failure bit I want to be sure
Model A1174 with 2 GHz Core Duo or Model A1207 with 2.16 or 2.33 GHz Core 2 Duo
Some symtoms of a dead logic board are as follows:
Drives spinning up
nothing displayed on the screen
no power throught USB (or the otherway around)
No Power Through firewire (or the otherway around)
fans running at max speed
computer heating up abnormally
display image distortion (prior to fail)
So if my MBP isn't showing any response when I hit the power button... no light, no fan, no optical drive activity, no HDD activity, no screen activity, no chime...
What might this be? Doesn't matter what the power source is, same response with battery and AC. I thought it was a bad logic board, but this makes me hope otherwise.
I have the same problem .
I was listening music and my Imac should down.
I try to turn it on but the computer should down after the apple symbol. After that no more turn on.
I opened and I notice the fans don't work, no video , no sound.
it have 4 led to indicate if everything is ok. all this led are good. Also I can hear the cd player working when I put some cd inside it.
What should I do?
I was listening to music on my MacBook Pro A1502,I went to the bathroom to have my bath came out from the bathroom and saw my MacBook off by itself…I tried the power button severally & it refuses to come on.
what could be the problem?
